![]() It allows you to directly enter and manipulate equations as well as coordinates. Moreover, this can be done with points, vectors, lines, and conic sections also. The idea is to connect geometric, algebraic, and numeric representations in an interactive way. Speaking of which, the advantage GeoGebra can offer over similar apps is that it provides multiple representations of objects that are all dynamically linked. 3 Term indices 3.This academic tool is a rather complicated application that is aimed strictly at those comfortable with difficult math. See Section 3 of the Darwin Core RDF Guide for details. Values for terms in the dcterms: namespace will depend on the details of the term. ![]() Terms in the dwc: and dc: namespaces are generally expected to have string literal values. The following namespace abbreviations are used in this document:ĭue to the requirements of Section 1.4.3 of the Darwin Core RDF Guide, terms in the dwciri: namespace MUST be used with IRI values. The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119. Label and the values of all other properties (such as Examples and Notes) are non-normative. The values of Term Name are non-normative, although one can expect that the namespace abbreviation prefix is one commonly used for the term namespace. In Section 4, the values of the Term IRI and Definition are normative. 1.1 Status of the content of this document Namespaces that contain only deprecated terms are not included in this document, but metadata about those terms can be retrieved by dereferencing their IRIs.įor a simplified list that contains only the currently recommended terms, see the Darwin Core Quick Reference Guide. ![]() Deprecation or supersession is noted in the term metadata. However, some terms in these namespaces are deprecated or superseded and should no longer be used. This document includes terms in four namespaces that contain recommended terms: dwc:, dwciri:, dc:, and dcterms. This document contains terms that are part of the most recent version of the Darwin Core vocabulary ( ). Biodiversity Information Standards (TDWG).
